Yes they can go bad, although often the wiring is the problem if a rodent gets at it. Make sure there is no damage. If there is, splice the wires back together

ive only used my switch for 3 months last year it was in my garage over winter months. the wiring seems ok ... im not getting accurate readings can you possibly recomend 1

this is what i have:

What readings are not accurate?

 

[jblizzle]

There are no readings. It is an on/off switch indicating if there is flow or not

im using a raspberry pi for my pool pump and using gpio (general purpose input output ) pins to "read" if the switch is open or closed....

when my pump is running im getting closed ... when pump is off i get open, closed,open,closed etc. im just asking if the switch is bad

thanks

Not necessarily. Depends where in the plumbing you have that switch mounted. Pic of you pool and plumbing and switch location would help.

things worked fine last year ...

You are using the flow switch for a purpose it was not designed for. You need to program around the noise of the switch chattering.

Either the switch spring lost a bit of tension or your water pressure increased.

You can try another switch.

can you possibly recomend another 1 ... did i get what i paid for only 26.00 ?

I understand that. When water is flowing the water pressure holds the switch closed. When water is not flowing a spring holds the switch apart.

Put the switch in a clear piece of PVC cut into plumbing at that point and you can observe what the switch is doing. You will likely see it moving when your pump is off.

I have not studied them for your use.

I agree that perhaps the spring lost some spring
When the water is not flowing, the spring should hold the contacts apart, perhaps they are too close together? You could just try bending the metal plate apart a little more.

I am not sure there is a better flow switch. They are very basic and work for the SWGs it was designed for.

No metal to bend on this one ...
